UNSPSC 31121212: Bronze sand machined castings

UNSPSC 31121212 Bronze sand machined castings is a Commodity code that encompasses cast iron and ductile iron components for water utility infrastructure, including pipe repair clamps and curb box assemblies procured by municipal water departments. State and local governments buy standardized replacement parts and repair components under this code — specifically stainless steel pipe repair clamps in multiple diameters, cast iron curb boxes with brass fittings and tar coating, and related water-main access equipment. The issuing bodies are primarily municipal water utilities, procuring through their finance or purchasing departments via RFQ. Recent activity shows the City of Madison Water Utility issuing multiple quotation requests for these cast and machined components.

The geographic spread is limited in recent activity to Wisconsin, where the City of Madison posted two RFQs on March 3, 2026, both due March 17, 2026. The first RFQ (551802026BG) sought 175 stainless steel pipe repair clamps across eleven line items ranging from 4"X8" to 12"X24" sizes, with acceptable manufacturers including Smith-Blair, Mueller, ROMAC, Ford, Cascade, Hymax, A.Y. McDonald, and JCM. The second RFQ (551702026BG) requested 150 complete cast iron curb box assemblies conforming to Bingham & Taylor model 94F specifications, plus 100 dust caps, 100 extensions, 100 top and bottom sections, 100 lids, and 50 repair lids. Both solicitations required FOB Madison delivery to 110 S. Paterson Street, firm pricing for one year, and 24-hour delivery notice. The City offered local vendor preference scoring to registered local suppliers but disclosed no explicit set-asides, budget ranges, or incumbent vendors. The source shows minimal recent activity outside these two March 2026 Madison solicitations.
